Abstract
The utility model provides a spray-type experimental device for a relation of gas flow rate and pressure intensity and relates to an experimental device. A pedestal is arranged in the bottom. A plastic bottle is fixed on the pedestal. A plastic pipe is inserted in a bottom cap of the plastic bottle. The plastic pipe is inserted to the bottom part of the plastic bottom. A ventilating hole is arranged in the bottom cap of the plastic bottle. An air hole plug is arranged in the ventilating hole. The spray-type experimental device for the relation of gas flow rate and pressure intensity is simple in structure and easy to manufacture and operate. Experimental phenomenon can be shown obviously and directly. Manufacturing raw material is easy to get and low in cost. Physical principles can be demonstrated clearly and understandable. The spray-type experimental device for the relation of gas flow rate and pressure intensity can also be used as a teaching instrument or a small extracurricular experimental instrument for students. The spray-type experimental device for the relation of gas flow rate and pressure intensity provided by the utility model is well-formed, and is elegant in color and nice in appearance, so that the spray-type experimental device for the relation of gas flow rate and pressure intensity has an artistic aesthetic effect and becomes a decoration on a table or in a cabinet. The spray-type experimental device for the relation of gas flow rate and pressure intensity has an enlarged application range and becomes a practical novel product.
Description
Technical field
The utility model relates to a kind of experimental provision, is specifically related to the experimental provision of a kind of atomizing gas flow rate and pressure relation.
Background technology
At present, be used for most experimental provision complex structure of physics teaching, the scope of application is wideless.And almost the basic principle of physics study is not tested and the experimental provision of making on the market, causing rigidly connecting tactile physical students in middle and primary schools can't be clear understandable to basic physics knowledge, add some theoretical property concepts physically, if do not explained orally analysis, be difficult to allow those students of begining to learn understand, thereby make most students forfeiture learning interest.Simultaneously, most physical experiment apparatus all can not as ornaments or handicraft puts on display.
The utility model content
Technical problem to be solved in the utility model is to provide that a kind of making simple in structure, easy, outward appearance are more art up, the obvious experimental provision of atomizing gas flow rate and pressure relation intuitively of experimental phenomena.
Technical problem to be solved in the utility model realizes by the following technical solutions:
The experimental provision of a kind of atomizing gas flow rate and pressure relation, it is characterized in that: the bottom is provided with base, be fixed with plastic bottle on the base, be inserted with a plastic tube on the bottle cap of plastic bottle, plastic tube is inserted to the plastic bottle bottom, bottle cap at plastic bottle is provided with air hole, is equipped with air plug on the air hole.
Described plastic tube top is taper, and the plastic tube upper end arranges nozzle.
Described air hole is located on the bottle cap of plastic tube one side.
The beneficial effects of the utility model are: the utility model making simple in structure, easy, easy to operate, experimental phenomena is obviously directly perceived, makes that raw material is easy to get, cost is low.Clear understandable with physical principle demonstration can be used as instruments used for education and uses, and also can be used as the extracurricular little experimental apparatus of student.Lines of the present utility model are beautiful clean, and color grace, outward appearance are dazzled extremely, and experimental apparatus is art up, become the ornament on the table, in the cupboard, and the purposes of experimental apparatus obtains expanding, and becomes practical novel products.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
The experimental provision of a kind of atomizing gas flow rate and pressure relation as shown in Figure 1, the bottom is provided with base 1, be fixed with plastic bottle 2 on the base 1, be inserted with a plastic tube 4 on the bottle cap 3 of plastic bottle 2, plastic tube 4 is inserted to plastic bottle 2 bottoms, bottle cap 3 at plastic bottle 2 is provided with air hole 5, is equipped with air plug on the air hole 5.Plastic tube 4 tops are taper, and plastic tube 4 upper ends arrange nozzle 6.Air hole 5 is located on the bottle cap 3 of plastic tube 4 one sides.
Open air hole, with suction pipe the nozzle level is blown, nozzle just has fog along with the air-flow face that blows penetrates, air-blowing must be more fast, and it is just more many more fast that fog penetrates, and clogs air hole, with suction pipe the nozzle level is blown, no matter how blowing does not have fog to penetrate yet.Illustrate that gas flow rate is more fast, pressure is more little.
More than show and described ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the instructions just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
